Hi, I have a greenworks 1600 psi 1.2 gpm. I understand it's a very small unit but I would like to clean my property without carrying the unit everywhere. Will the Karcher 1/4 inch extension hose with the m-22 fit on my machine? Also, if I attach an extra 150-200ft of hose will I lose pressure? Thank you in advance. Thank you very much for your help.

Answer
Unfortunately, we do not carry an extension hose available for the Greenworks model. It does not use the standard 14MM M22 pressure washer connection. I would recommend reaching out to the folks at Greenworks to see where one can be purchased. They can be reached at 888-909-6757

Hi Bill, I'm interested in extending the hose that my washer came with (Simpson MSV2600) but I don't know which adapter (if any) I need. Both ends of the hose I have are female ends. (Hope that question made sense!) Thanks for your help.

Answer
You can definitely use this Karcher hose as an extension hose for your machine. The connection fittings will be compatible. We also carry a couple different hoses that would be compatible with your set up. I am referring to the models EXT102F1 and PW1021. All three hoses will work for what you are trying to accomplish

Hi Bill, I have a Karcher G 2500 VH with a 25' hose. I would like to extend/replace it for a 50 Hose. Can you please tell me the options? Thanks, Mark

Answer
You could use this hose to use as an extension. The only issue you may have would be if the connections don't match up. In some cases the pressure washer that you have may have quick connect fittings and, so adapters would be needed. Your other option would be to just go with a 50' hose.

Thanks,
